Sed Tutorials

If you have written anything about sed - whether an introduction, how sed got you out of a
real-life situation, or perhaps an advanced technique you've discovered - you may like have
your work published here. Your contribution will be very
welcome.

Part 1 of Greg Ubben's analysis of a complex sed script he wrote to sort, delimit and
number an input file containing tabulated data. Lookup tables are a powerful technique
for the serious seder's armoury.

Part 2 of Greg's script analysis looks at how he implemented a counter using lookup
tables. This complex problem is described step by step from the basics, following through
Greg's reasoning until we finally reach the solution.
